Question

Five point charges, each of value +q coul, are placed on five vertices of a regular hexagon of isde L meters. The magnitude of the force on the point charge of value -q coul, placed at the centre of the hexagen is…………….

Answer 1

Correct Answer - A::B::D

Force on `(-q)` due to charge at D will get cancelled out by force on `(-q)` due to change on A. ismilarly force on `-q` due to charge at E will get cancelled out due to charge on B. So the net force will be because on C `F=(1)/(4pi in_0)(q^2)/(L^2)` directed from O to C.
